Gṛhastha-vṛtti and Niyama: Models of Householder Livelihood and Discipline (गृहस्थवृत्ति-नियमाः)
एतत् प्रज्ञामयैर्धीरा निस्तरन्ति मनीषिण: । प्लवैरप्लववन्तो हि कि करिष्यन्त्यचेतस:
etat prajñāmayair dhīrā nistaranti manīṣiṇaḥ | plavair aplavavanto hi kiṁ kariṣyant acetasaḥ ||
かくして、堅忍にして識別ある賢者は、智慧より成る舟をもって（時の危うき流れと世の災い）を渡り越える。だが、そのような舟を持たぬ者――分別なき人々は、いったい何をなし得ようか。
